these transporters should not be addressed by such an inhibitor. A high-throughput screen against a library of ∼3 million compounds was performed to find a small molecule with this challenging potency and selectivity profile. The N-(1H-pyrazol-4-yl)quinoline-4-carboxamides were identified as an excellent starting point for further compound optimization. After extensive structure-activity relationship explorations
尽管众所周知的事实是,即使在正常的氧气供应条件下,促进性葡萄糖转运蛋白GLUT1仍是保证许多肿瘤实体葡萄糖消耗增加的关键因素之一(被称为Warburg效应),但仅进行了很少的努力寻找一种GLUT1选择性小分子抑制剂。由于GLUT1家族的其他转运蛋白都参与关键过程,因此此类抑制剂不应解决这些转运蛋白。针对约300万种化合物的库进行了高通量筛选,以发现具有这种具有挑战性的效能和选择性的小分子。N-(1H-吡唑-4-基)喹啉-4-羧酰胺被确定为进一步优化化合物的理想起点。经过广泛的构效关系探索后,获得了对GLUT2,GLUT3和GLUT4的选择性因子> 100的个位数纳摩尔抑制剂。最有前途的化合物BAY-876 [N4- [1-(4-氰基苄基)-5-甲基-3-(三氟甲基)-1H-吡唑-4-基] -7-氟喹啉-2,4-二甲酰胺]在体外具有良好的代谢稳定性,在体内具有较高的口服生物利用度。
